摘要： A process for the preparation of ascorbic acid-2-phosphate, which comprises reacting ascorbic acid or araboascorbic acid with a phosphate donor other than ATP in an aqueous medium in the presence of an effective amount of an enzyme derived and capable of preferentially catalyzing the enzymatic phosphorylation in the 2-position of ascorbic acid or araboascorbic acid by said phosphate donor, and recovering the resultant ascorbic acid-2-phosphate from the reaction solution.

摘要： 5ʹ-guanylic acid may be produced with higher yield by an enzymatic reaction using, as a source of enzyme, fermented product such as fermented liquor and microbial cells obtained by culturing a transformant of Escherichia coli which is capable of producing 5ʹ-guanylic acid from 5ʹ-xanthylic acid, adenosine-5ʹ-triphosphate and at least one substrate selected from ammonia and glutamine and which is produced by transformation of a strain of E. coli carrying a temperature-sensitive cl repressor with a novel recombinant plasmid prepared by recombination of a DNA fragment carrying the P L promoter located upstream of a gene of 5ʹ-guanylic acid synthetase with a vector DNA. It is possible to culture the transformed microorganism in a medium containing 5ʹ-xanthylic acid, adenosine-5ʹ-triphosphate and at least one member selected from ammonia and glutamine.
